Hi,
I'm the maintainer of Sig-Infra in openEuler community. Sorry to bother you.

Our mail list system has a few problems that are not convenient to use.
1. Emails sent by unregistered users will be blocked and they cannot be handled in time.
2. If a certain mailbox in the mail list reject the mail, we will directly reply the mail to the sender, which may cause misunderstanding.

According to these two issues, the current approach is as follows:
1. Blocked emails will be processed regularly, but they may not be timely.  We hope you can register and send them again.
2. The operation methods of other open source communities are being researched. It is hoped that  maillist can be easily used as soon as possible.

Your suggestions are welcome.
